custom friends lists on ipad Facebook app are gone

I used to be able to see my Facebook custom lists for friends, family etc using my iPad app by going to: more, explore, feeds and I would see all of my lists as well as 'most recent'. Now I only see 'most recent', all my custom friend lists are gone. I have logged out, deleted and reinstalled the app (yes, it is the most current app), hard booted the iPad all to no avail. I am on iPad Air 2 iOS version 11.2.6 My husband has the same iPad, same version iOS, FB app up to date and all his custom lists are there. Any ideas, short of doing a restore?
